Celtic researcher Edward Davies deemed Creirwy "the Proserpine of the British Druids"—also comparing her mother Ceridwen to Ceres of Roman myth.
[2] Mythographer Jacob Bryant theorized that Creirwy and Ceridwen were essentially "the same mystical personage.
[4] For the ancient Druids, the mundane egg allegedly symbolized chaos, the beginning of all things, and upon it oaths were administered.
According to hagiographies of Winwaloe, Saint Creirwy (Latin: Creirvia; Breton: Klervi) as a young girl had one or both eyes gouged out by a wild goose, but Winwaloe retrieved the eyeball(s) from the gander's belly and returned it/them to his little sister's orbit(s), and Creirwy's eyesight was miraculously restored.
[6][7] However, the legend is dismissed by Baring-Gould and Fisher, who say it originated with an expression that "Creirwe" used; supposedly she would often say she "owed her eye to Winwaloe", but in reference to a much more ordinary childhood event, in which her brother stepped in and protected her when a wild goose flew at Creirwy and almost pecked out her eye.
